LSQUIC is an open-source C library implementing the QUIC transport protocol and HTTP/3 for both servers and clients, used in production by LiteSpeed web server products. It supports QUIC v1/v2, RFC 9000-9002, RFC 9114 (HTTP/3), QPACK, and extensions like WebTransport and unreliable datagrams.
Use cases
- add HTTP/3 support to a C or C++ server
- build a custom QUIC client in C
- implement WebTransport over HTTP/3
- test QUIC protocol compliance and interoperability
- embed QUIC transport in an existing network application
- serve HTTP/3 with QPACK compression
When to choose
- you need a mature, production-proven QUIC/HTTP-3 implementation in C
- you want broad RFC coverage including QUIC v2 and WebTransport
- you are building a high-performance server or client on Linux, macOS, Windows, or FreeBSD
When to avoid
- you want a higher-level language binding rather than a C API
- you prefer a pure userspace Rust or Go QUIC stack for memory safety
- you only need HTTP/2 or TCP-based transport
